I'm in the office, which is on the opposite end of the house from the living room. DH is in the living room, in his recliner, with his feet up. He's watching some program on the military channel. Just now Jax, our older GSD, started heaving like he was about to throw up - right in front of DH. DH never heard it. I heard it from the opposite end of the house and managed to get Jax out the back door just in time. Truth is, I would have heard it if I had been sound to sleep - in the next county! How can a man be so observant when he's working, yet so tuned out when he's watching TV?!?
